Like many of you, I'm already looking for "upgrades" to my ShapeOko (the one that I haven't even built yet
The Wolfgang Engineering spindle looks beautiful -- both in terms of design and functionality (he had makes them!):http://www.wolfgangengineering.com/Spindles.php
Has anyone pondered this as an upgrade? Or does anyone own one? He's offered to create a custom mount in aluminum as part of the order, which is great in itself. I know it's $289 for the kit, but I *really* want to be able to mill aluminum and he indicates he doesn't see a problem with this on a ShapeOko.
I'd also be prepared to upgrade my stepper motors to NEMA23s for more torque in conjunction with this to get to the holy grail of metal milling....
Any thoughts or comments welcome.
